Why don't we just (natural) oil high grade luthier guitars ? I mean nobody will ever carry a 3000$ guitar to a camp fire.
It will just get dirty or stainy over time like the player himself. Also it is easy to clean/sand and re-oil it from time to time.
My stubborn grandpa always used oil and wax for his lutes and nothing could make him do it different.

Thanks for updates. I no longer am pursuing the refinish. I'm glad I didn't as I was just about to post something about My Cordoba C10 today !! But I do want to say: I wonder if a hot air gun could potentially loosen the glue at bridge or purfling ...M
